The sea-crossing bridge connecting the mainland of Ca Mau with Hon Khoai Island has been speeding up its progress since the first months of implementation. This is the largest-scale project in the Mekong Delta region, expected to create a breakthrough in transport infrastructure, logistics and marine economic development for the southernmost region of the country.
According to the investor, the bridge is built according to sea-crossing bridge standards with a total length of more than 18.22 km, including a 17.3 km long main bridge and a 0.87 km long branch bridge connecting to the island.
The project has a cross-section of about 17.5 m wide, 4 lanes, and a design speed of 80 km/h. The starting point of the project connects to the Ca Mau - Dat Mui highway and the Ho Chi Minh road in Dat Mui commune (old Ngoc Hien district), the end point stops at point K10, the eastern shore of Hon Khoai island.
With a record length across the sea, this is considered the longest bridge in Vietnam and the third longest in Southeast Asia. The total investment capital is about 100,000 billion VND, demonstrating great determination in opening up the economic and social potential in the southernmost region. In the picture is a team of engineers and workers busy working in the middle of the sea, aiming to bring the project to the finish line on schedule.
According to VTC News Electronic Newspaper reporters, in mid-November, at the connection point with the Ca Mau - Dat Mui Expressway, many construction machines and equipment were gathered by the contractor.
The team of engineers and supervisory consultants are carrying out the work of leveling the ground and erecting casing pipes to prepare for the construction of bored piles - one of the foundation items for the construction of the bridge body. This is the first phase so most of the time is spent on preparation, testing and technical inspection.
An engineer at the construction site said the pile drilling process was 88-100 m deep. After nearly 3 months of construction, many key equipments have been put into stable operation, ensuring technical parameters for the implementation of the next steps.
In the offshore area, the construction site is equally bustling. The construction unit mobilizes large tonnage ships to pull floating barges Zack-up to serve hydraulic drilling and offshore pile construction.
At the same time, the team of workers is pouring concrete piles under complex weather conditions and constantly changing tides.
In addition to the road and bridge route, the Hon Khoai dual-use port project has also been started and implemented synchronously. The port has a construction scale of a 1,000 m long wharf, a design capacity of 20 million tons/year, and can receive ships of up to 250,000 DWT. The project includes dredging, opening a new shipping channel about 5,000 m long, 230 m wide and a turning basin with a diameter of 800 m. The total investment is expected to be about 15,000 billion VND.
With its prime location on the international shipping route, Hon Khoai Port is expected to become an important trade gateway for Ca Mau in particular and the Southwest region in general. The appearance of a large-scale deep-water port will open up opportunities for strong development of the logistics service sector - which is still limited in Ca Mau due to the lack of connecting infrastructure.
When the two components - the sea-crossing bridge and Hon Khoai General Port - are completed, the Dat Mui area will possess a key infrastructure system, creating momentum for the development of the marine economy, trade, services and tourism. Experts say this is a series of strategic projects of breakthrough significance, with a profound impact on the development space of the entire southernmost region.
The simultaneous implementation of two large-scale, technically complex projects demonstrates the great efforts of the relevant units in realizing the marine infrastructure planning. The clear changes on the construction site in recent times show that the project is on schedule and will continue to be promoted in the coming time.
Hon Khoai sea-crossing road and bridge, when completed, will not only shorten the distance to the island but also open a new door for international trade, develop logistics, and create a foundation for Ca Mau to make a breakthrough in the coming period. This is also considered a strategic step in the process of exploiting the potential of the sea and islands and strengthening the connectivity capacity of the southernmost region of the Fatherland.
